Cherry laurel plant named &#39;JONG2&#39;

ABSTRACT

A new cherry laurel plant particularly distinguished by being winter hardy, having healthy growth, and a compact and bushy habit, is disclosed.

Genus and species: Prunus laurocerasus.

Variety denomination: ‘Jong2’.

BACKGROUND OF THE NEW PLANT

The present invention comprises a new and distinct variety of Cherrylaurel plant, botanically known as Prunus laurocerasus, and hereinafterreferred to by the variety name ‘Jong2’. ‘Jong2’ originated from anopen-pollination conducted in Biezenmortel, The Netherlands in 2006between un-named and unpatented Prunus laurocerasus plants.

The seeds from the cross were sown and plants were grown outdoors forevaluation, where an individual plant designated ‘Jong2’ was selectedfrom the group of plants in Biezenmortel, The Netherlands in May 2007.In October 2007, ‘Jong2’ was first vegetatively propagated by softwoodcuttings. ‘Jong2’ was found to reproduce true to type in successivegenerations of asexual propagation via softwood cuttings.

SUMMARY

The following are the most outstanding and distinguishingcharacteristics of this new variety when grown under normalhorticultural practices in The Netherlands.

1. Winter hardy;

2. Healthy growth; and

3. Compact and bushy habit.

DESCRIPTION OF THE PHOTOGRAPHS

This new cherry laurel plant is illustrated by the accompanyingphotographs which shows the plant's overall plant habit including form,and foliage. The photographs are of a two-year-old plants grown outdoorsin The Netherlands in March 2015. The colors shown are as true as can bereasonably obtained by conventional photographic procedures.

FIG. 1 shows the overall plant habit of ‘Jong2’.

DESCRIPTION OF THE NEW VARIETY

The following detailed descriptions set forth the distinctivecharacteristics of ‘Jong2’. The data which define these characteristicswere collected from asexual reproductions carried out in TheNetherlands. Data was collected on two-year-old plants grown outdoors inThe Netherlands in March 2015. The range of day temperatures was 10° C.to 25° C. and the range of night temperatures was 6° C. to 14° C.
